Breaking bonds: Double-helix unzipping reveals DNA physics sissaschool physrevlett

System setup. Typical configuration of a DNA chain of 500 base pairs as it unzips during the driven pore translocation of one of its strands.

Translocation is driven by the external force, which exclusively acts on the DNA tract in the pore. A magnified view of the pore entrance is shown in the inset, where the random DNA composition is color coded as in the legend. Translocation traces. The traces show the time evolution of the index of the nucleotide at the pore entrance
